I would read Truce at Bakura. Being directly after ROTJ it's sets the stone for EU (even though Zahn and TTT started it all ) So, yes, I would read that.

But . . . Children of the Jedi? I, personally, did not enjoy that book or any of the following ones in the Callista triology (Darksaber and Planet of Twilight) So, I wouldn't read it again, but of course . . . the choice is yours
